Clinical Trial Summary
The aim of this study was to evaluate the efficacy of caffeine and alpha-lipoic acid in the
treatment of burning mouth syndrome by symptom assessment with visual analogue scale.
Description:
The etiology of BMS is multifactorial, involving a complex interplay of neuropathic,
psychological, neuroendocrine, and immunological factors. Neurologically, BMS has been
categorized into three subtypes: peripheral small fiber neuropathy, subclinical trigeminal
neuropathy, and inhibitory dopaminergic deficiency. Neuroimaging and peripheral nerve studies
have further implicated altered brain activation patterns and increased expression of
specific receptors like TRPV1 and P2X3 in the pathogenesis of BMS. Hormonal imbalances,
particularly in estrogen levels, have also been suggested to contribute to contribute to the
condition.
Caffeine, a xanthine alkaloid chemically known as 1,3,7-trimethylxanthine, is recognized for
its diverse biological functions. As a central nervous system stimulant, its primary
mechanism involves antagonizing adenosine receptors, thereby enhancing the release of
neurotransmitters such as dopamine and norepinephrine, which are known to play roles in
analgesic pathways. Caffeine is also noted for its neuroprotective properties and is
theorized to reduce the risk of neurodegenerative diseases. It affects the central processing
of pain and is involved in regulating circadian rhythms and sleep-wake cycles. Additionally,
caffeine has mild anti-inflammatory properties. Its stimulatory effects may also improve mood
and cognitive function.
